Abstract (en)
[origin: WO2007144576A2] A UV absorbing polymeric composition has an E<SUB>308</SUB>/E<SUB>524</SUB> and/or E<SUB>36O</SUB>/E<SUB>524</SUB> ratio of greater than 4, and contains an organic resin and zinc oxide particles. The composition is particularly suitable for use in producing an end-use product, preferably in the form of a polymeric film, exhibiting UV absorbing properties and improved transparency. In one embodiment, the composition may be produced from a masterbatch composition containing an organic resin, an organic dispersing medium and zinc oxide particles. The masterbatch is preferably prepared by mixing a pre- dispersion of the zinc oxide particles in the organic dispersing medium, with the organic resin.
